T o all whom it may concern Be it known that I, CHARLES H. VOGEL, a

subject of the King of England, residing in it in letter-feeding'direction, and also to en` able the carriage to be returned easily andreadily -from any point. Y

I attach a rod with an armature to the typewriter carriage. The rodextends in the direction of travel of the carriage, and the armature isguided along a table or shelf "upon which are mounted electro-magnetspreferably arrangedin two rows, between which the armature moves.Connected with vthe armature, I provide a rocker having two so as toclose circuits through the electro-' magnets in the rear or in advanceof the traveling armature; holds in contact lwith the table, thatcontact shoe which is remote from the typewriter carriage, so that theaction of the magnets is normally to advance the armature' and thecarriage in the letter-feeding direction, that is. from right to left,exerting a tension which advances the carriage through a lettcr-'spacewhenever thecarriage escapement lisoperated. By depressing acarriage-return key, the position of. the rocker is reversed, so as 'todepress thecontact shoe which is upon the lside of the armature adjacentto the carriage. The niagnetsto the left of the armature then becomeinactive,

'and the magnets immediately to the rightVA become energized' and drawthe armatureY toward the right; as the armature advances, the activecontact shoe slides along the table i and closes other contacts more inadvance of the armature; in thisway, the armature will A spring normallySerial VNo. 624,918.

of the carriage. In the accompanying drawings, Figure 1 is a plan of thecarriage-feeding and returnbe drawn along, so as to complete the returning device, showing part of the carriage to which it is attached, partsof the returning device being broken away. Fig. 2 is a longitudinalsection through the feeding and returning device, taken on .the line 2 2of F ig. l. Fig. 3 is a part elevation and cross section through-thetable which supports the electro-magnets of the feeding and returningdevice.

A carriage 1 is controlledin'its movement from right to left by anescapement 1a. At

a suit-able point, such as the left-hand rear 'portion of.` thecarriage, I attach a rod 3,

.which extends in the direction of travel of ythe carriage, and on theend of this rod is carried an armature 5, in the form of a block havinga guide spline '19, which runs in a groove 20 in the upper 'face ofatable or` shelf 4. The armature 5 travels between two rows ofelectrdmagnets C, which are connected bymeans of conductors 15, tomains-16; said mains being in circuit with a battery 17 or other sourceo t' current. rl`he armature 5 is provided with a laterally project-ingstem 11, carrying a 'rocker 10 inthe form of a bow, as shown in Fig. 2,the end of the bow llying adjacent to the table, and being provided withpivotedeontact slices 13 and 22. A spring 21 normally holds the shoe 22on v,the face of the table, so that it may bridge ,one or more pairs ofcontacts 14, with whiclrthe Aconductors 15 connect. In this way, acircuit is normally closed through one or more pairs of magnets at theleft of the armature 5, the opposite magnets of the two rows beingconnected by conductors 18 for this purpose.

On the upperside of the rocker 1 0, .a lug 12 is provided, and as thearmature travels to and fro, this lugtravels along-under a bar 9, whichextends longitudinally of the table, and is supported on arms 9a pivotedat 4* on posts 4, which extend rearwardly from the table 4C. At aconvenient point, a ret-urn key 7 rests upon the bar 9, preferA 4ably atthe right end thereof, which is ad` jacent to the carriage 1. This keyis piro' ally supported at 8, as shown in Fig. and when it is depressed,it depresses the bar 9 which contacts with lug l2, and rotates the `25ture.

o thereby reversed, and theI armature moves toward the right to returnthe carriage.

n account ofthe spring 21, the shoe w22v is normally held on the table,so that two or Y more electro-magnets atthe left of the arma-I 5 tureare normally active, and normally exert a tensiofi on the carriage,coperating with the e.i;..ipement.1a to give the carriage its" feedingmovement.

Having thus described my invention,` I
